Are alternate universes the cause of dark energy and the nonzero cosmological constant?

   If the cosmological constant arises from a form of dark energy which has negative pressure equal to its energy density, then does dark energy prove that alternate universes exist? If energy and spacetime are a single conglomerate, with the multiplicative product of energy, volume, and time always equal to an integral multiple of the granularity in the Fredkin-Wolfram information process of alternate universes, then what? Are strings merely the tubular computations of the Fredkin-Wolfram process as it twists, turns, untwists, and unturns across alternate universes? Does quantum gravity theory fail without alternate universes and the Fredkin-Wolfram physical constant? Can the cosmological constant be approximately calculated in terms of Newton's gravitational constant, the speed of light, Planck's constant, and the Fredkin-Wolfram constant?
